I have c++/c application with a lots of unit tests. I would like to get overall coverage and also individual coverage of each test with condition that each test can be run o

Answer 1

The simplest utility I've found for merging Cobertura files is cobertura-merge via NPM.

Usage:

npm install cobertura-merge
cobertura -merge -o output.xml package1=input1.xml package2=input2.xml

Or it can be used directly without installing through npx:

npx cobertura-merge -o output.xml package1=input1.xml package2=input2.xml

Examples sourced from the GitHub README for cobertura-merge.
